In 1863, at the age of 17, Wong set up his first martial arts school in Shuijiao. 26 years later, in 1886, he opened his Po-chi-lam (寶芝林; Baozhilin) clinic at Ren'an. In 1919, Wong was invited to perform at the Chin Woo Athletic Association's Guangzhou branch during its opening ceremony.

Wong died of illness on May 24, 1924 in Chengxi Fangbian Hospital in Guangdong. He was buried at the foot of Baiyun Mountain. Wong's wife, Mok Kwai-lan, and his two sons, along with his students Lam Sai-wing and Dang Sai-king (鄧世瓊; Deng Shiqiong), moved to Hong Kong and established martial arts schools there.

Wong was a master of Hung Gar (also called Hung Fist). He systematised the predominant style of Hung Gar and choreographed its version of the Tiger Crane Paired Form Fist, which incorporates his Ten Special Fist techniques. Wong is famous for using the Shadowless Kick. He named the techniques of his skills when he performed them.

Wong was adept at using weapons, such as the staff and southern tiger fork. One tale recounts how Wong defeated a group of 30 gangsters on the docks of Guangdong with a staff.[citation needed]

Wong is sometimes incorrectly identified as one of the "Ten Tigers of Canton". His father Wong Kei-ying was one of the ten but he was not. Wong is also sometimes referred to as the "Tiger after the Ten Tigers".[4]

Over 100 films and television series featuring Wong Fei-hung have been produced since 1949, mostly in Hong Kong. Cantonese actor Kwan Tak-hing starred as Wong in over 70 films between the 1940s and 1980s and earned himself the nickname "Master Wong". Other prominent actors who played Wong Fei-hung include: Jet Li, in the Once Upon a Time in China film series; Vincent Zhao, in the television series Wong Fei Hung Series.

Wong Fei Hung Series (1996) is a Hong Kong television series on five stories about Wong Fei-hung. The series was produced by Tsui Hark and starred Vincent Zhao as Wong Fei-hung. This television series is sometimes regarded as a television series counterpart to the Once Upon a Time in China films.

Shaonian Huang Feihong (2002) is a Chinese television series featuring Wong Fei-hung as a youth.

A rearranged version was rewritten and performed by Dayo Wong as the theme song of Men Don't Cry. Taiwanese singer Kenji Wu performed a song titled On the General's Orders but the tune is different from the original one.

Fei Fong Wong, the lead character in the Square video game Xenogears, was named after Wong Fei-hung (his name being written the same in katakana as Wong's name is written). Another protagonist, Citan Uzuki, closely resembles Wong, being both a physician and martial artist dressed in traditional Chinese garments.

In Will Thomas' third mystery novel, The Limehouse Text, his Victorian detective Cyrus Barker trained in martial arts in Guangdong under Wong Fei-hung's tutelage.

Stan Sakai has mentioned his plans to include a character based Wong Fei-hung in a future issue of his comic book Usagi Yojimbo.
